摘要
提出了一种新型的适合于工程应用的直接寻优法──旋转矢量法。特别适用于求解具有复杂约束的非线性寻优问题。通过矢量绕目标值较低的端点的旋转和矢量的不断缩短，逐渐收敛到最；优点。另外，由于本法中采用了旋转换索的基本寻优结构，因此，很容易将此法推广到求解离散问题上。如果再辅以其它启发式信息，则可大大提高搜索率。通过大量的实例验算证明了其有效性。可靠性和通用性。具有较高的研究价值和应用前景。
A new optimization method applied to the engineering design called as rotate-ve-ctor meihod is put forward which is proper to solve the nonlinear plan problem with restrai-nts. Through making use of the vector's rotating around the low terminate point and contrac- ting, the vector is converging step by step, and the optimization point can be obtain at last.with great deal of examples being worked out, the new niethod has proved valid, availableand general purpose.
